Probing the Local Bubble with Diffuse Interstellar Bands. III. The Northern hemisphere data and catalog

Abstract

We present a new high signal-to-noise (S/N) observations of the Diffuse Interstellar Bands (DIBs) in the Local Bubble and its surroundings. We observed 432 sightlines and obtain the equivalent widths of λ5780 and λ5797 \ DIBs up to distance of 200 pc. All observations have been carried out by using Intermediate Dispersion Spectrograph (IDS) on 2.5 m Isaac Newton Telescope, during three years, to reach a minimum S/N ratio of 2000. All λ5780 and λ5797 absorptions are presented in this paper and the observed values of interstellar parameter; λ5780, λ5797, Na I D lines including the uncertainties are tabulated.
